The GS1AHT150 is an external frontal rotary handle from the TeSys GS range, designed to operate the GS series disconnect switches rated 630 A to 800 A per IEC standards. It gives you a three-position handle (Test-O-I) with a black front plate — the Test position lets you check auxiliary contacts without closing the main power contacts, which saves time during commissioning or troubleshooting.
Integration notes
Front-mount design means the handle plate sits on the enclosure door, coupling to the switch mechanism inside. The black handle and plate are a visual match for standard TeSys GS enclosures.
